4 Claims. (Cl. 193- 42) This invention relates to an adjustable supportmeans, and more particularly to a horse having adjustable height.

Another object of the invention is to provide a device for holding heavybar stock during cutting, drilling or other processing thereof, andhaving a roller thereon for supporting the bar stock and permitting easymovement thereof.

It is still another object of the invention toprovide the ends of theroller with radially projecting annular flanges whereby the barstock'being processed contacts the rotating flanges when it is movedrather than rubbing against a stationary flange on the frame of thedevice as is conventional.

Another object of the invention is to provide a horse for supporting barstock having a roller with a flange thereon for supporting the stockwhereby the stock may be easily maintained in alignment duringprocessing.

Still another object of the invention is to provide a horse having aroller for supporting bar stock wherein the roller is of relativelylarge size thereby permitting heavy stock to roll thereon more easilythan where smaller rollers are used.

Another object of the invention is to provide an adjustable horse whichis economical to manufacture, durable in use and easy to maintain.

Still another object of the invention is to provide a horse having anovel adjustment means thereon mounted laterally between the legsthereof.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FEGURE 1 is a perspective view of the invention;

FIGURE 2 is an elevational cross sectional view taken substantially onthe plane of line 22 in FIGURE 3; and

FIGURE 3 is a plan view of the invention partially in section.

Referring to the drawings, particularly FIGURE 1, it can be seen thatthe horse comprises four sloping legs 1%), 12, 14 and 16 which aresubstantially identical in size and construction. Since the legs aresubstantially identical in construction, only the leg 16 will bedescribed in detail.

The leg 16 comprises an angle member 18 which may be formed of stockangle iron cut to the desired length. The angle member 18 has an insideflange 19 which extends vertically and has a circular disk 26 cut fromtwo and one-half inch round stock welded thereto. Bolted to the upperend of the flange 18 is a roller support plate 22. The upper flange 24of the angle member 18 has a bracket comprising a short piece of angleiron 26 bolted thereto adjacent its lower end by means of bolts 28.

The leg 1% is a mirror image of the leg 16 and constructed in anidentical manner.

The upper ends of the legs 16 and are fixed to gether by means of ahorizontally extending angle member 30 welded thereto. Mounted betweenand welded to the lower end of the legs 10, 16 is a second horizontallyextending angle member 32.

Parallel to the angle member 32 and spaced slightly thereabove is ahorizontally extending channel member 34 having studs, 36, 36' weldedwithin its end portions and projecting slightly therebeyond. The ends ofthese studs are threaded and extend through apertures in the brackets orangle members 26, 26 and are locked to the angle members by means of thenuts 38, 3S threaded on the studs.

An inverted V-shaped handle member ll has horizontally extending lowerends projecting through aperture in the upper ends of the brackets 26,26' and thereby pivotally supporting the handle on the legs. The handlehas an upper integral horizontally extending portion 42 that normallysnaps under and is retained by the upper flange of the angle member 30.

The legs 12, 14- are substantially identical to the legs 10, 16 exceptthe lower ends of the legs have rotatable wheels mounted thereon. Thelower ends of these legs have short angle pieces 5% 5t) and weldedthereto so as to form a box section. Recesses are formed between thelower ends of the legs and the angle pieces Ell, 5t?" so as to receiverotatable wheels 44, 44 also formed by cutting from two and one-halfinch round stock. The horizontally extending pins 54, 54 fix the wheelsrotatably to the legs.

The parallel legs 14, 12 are also rigidly held together by means of twohorizontally extending angle members 58 and 6t) and a channel member 52.The members 5%, 6t), and 62 are secured to the legs 14 and 12 in thesame manner in which the members 30, 32 and 3d are secured to the legmembers 16 and Til The four roller support plates 27. have holes drilledin the upper ends which are in line so as to receive a rod 64 threadedon its ends and retained on the legs by nuts 66, 66.

The rod 64 is preferablyoue inch in diameter and the cylindrical tubularroller 7% is preferably four and a half inches in outside diameter. Asshown in FIGURE 2, a one inch thick square plate or block 72 is weldedwithin the roller 70 at each end thereof. The block 72 is preferablywelded at its corners to the inside of the roller. After the plates 72are Welded in place, the flanges 73 and 74 which are preferably ofthree-eighth inch stock are also welded adjacent the plates '72 and ontothe ends of the roller 70. Holes are then formed in the blocks 72 andflanges 73 and 74 which are just large enough to permit the roller 7% torotate freely on the rod 64. Mounted between the ends of the blocks orroller and the plates 22 are washers 76, 76'.

The operating mechanism 79 comprises two parallel horizontally extendingrods 3% and 82 having both of their ends threaded. As viewed in FIGURE1, the left ends of the rods are rigidly attached to the horizontallyextending channel member 62 by means of nuts 84-, 86, 88, 90 whichtightly grip the channel member. After the nuts are tightened, they arethen welded in place. A box member 92 is formed by welding together twoshort pieces of angle iron. This box member has three parallelhorizontally extending passages drilled therethrough. The rods and 82are then extended through the two outer holes in the box member 92 andthen have nuts 94 and 96 respectively threaded thereon. These nuts arethen welded to the rods and to the box member 92 thereby rigidlyconnecting the rods to the box member. Two nuts 98, 98 are then weldedover each end of the central bore through the box member 92. A crank 1&2has a threaded extension 164 which extends through an aperture orhorizontally extending bore in the center of the channel member 54. Thethreaded extension 1% is screwed through the nuts 93 and 98' and thenhas a stop nut 106 threaded on and welded to its end. The nuts 100, 1%are threaded on the extension 1% so as to snugly embrace each side ofthe channel member 34. After these nuts 1%, til-ll are properly locatedthey are rigidly welded to the extension 104. The washers lilll,

3 161 are inserted between these nuts and the channel member.

In operation, the roller 70 supports bar stock 108 and permitslongitudinal movement thereof since the roller can rotate freely onshaft 64. Also, the flanges 73-, 74

on the roller prevent the bar stock from falling ofi the roller when itcontacts the flanges, very little friction is produced between theflanges and the bar stock as in conventional devices wherein the flangesare fixed.

To adjust the elevation of the roller 70, it is only necessary tooperate the crank 1H2. whereby the threaded extension W4 screws into'orout of the non-rotatable nuts 98', 98' to force'the lower ends of thelegs either together or apart. Since the circular plates 20 on the lowerends of legs 16 and are fixed to the legs, these legs do not move,however, legs 12 and 14 are free to move on rollers 44 and 44'. Thefixed circular plates also act as a brake for the entire assembly andprevent unnecessary movement thereof. However, by pulling downoperatingdevice 79, the bar stock 108 may be easily lowered or raised to anydesired elevation.

The foregoing is considered as illustrative only of the principles ofthe invention. modifications and changes will readily occur to thoseskilled in the art, it is not desired to limit the invention.
